More than 45 years of professional manufacturing experience, WUXI TBS SCIENCE AND TECHNOLOGY CO., LTD have been one of the leading manufacturer in China,mainly specialize in ERW Tube&Pipe Mill Line, Slitting Line, Cut To Length Line, etc. Throughout many decades team efforts for improvement of superior product quality and pursuit of advanced technology, we have widely won high praise from domestic and overseas customer. We always keep strong faith in “Thinking for what customer think”. Our mission: “Customized Technical Support,Most Cost-Effective Commerical Solution,High Performace Machine Supply,Reliable Service After-Sales” TDG Series Directly Forming to Square and Rectangular Tube Mill Only one set of rollers can be continuously produced within a certain range of rectangular steel pipe, using the international advanced multi-radius combination molding process and high-frequency welding, forming by multi-channel symmetrical bending. It can be divided into small side bending, boardside bending, free bending at closed side, high frequency welding, precision straightening, produce the exact size and good quality pipe after cut off. Characteristic： ·One set mold roller can produces a range of rectangular tubes. ·This machine has characteristics such as no replace spindle, no remove roller stand and quick change rollers. ·Save mold, save time. ·Four square corner deformation part which can save extra deformation process then save energy consumption and equipment load.
